To all whom it may concern Be it known that I, HUGH OSBORNE, a subject of the King of Great Britain, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Paper-Polishing Machine, of which the following is a full, clear, and exact description.

My invention relates generally to paper polishing machines and more particularly itis directed to a new and improved structure comprising cooperating parts whereby the pressure of the movable stone may be adjusted so that the operation of the parts may be rendered more efficient.

A further object of my invention is to provide a new and improved paper polishing machine made up of two parts which are simple in their structure, the machine presenting advantages in construction and operation and also providing for the production thereof at a low cost.

Other objects and advantages of the invent-ion will appear as the description thereof proceeds, all of which is particularly pointed out and included in the appended claims.

Reference is to be had to the accompanying drawings forming a part of this specification in which similar characters of reference denote corresponding parts in all the views, and in which- Figure 1 is a perspective view of the machine with the movable stone in inoperative position; Fig. 2 is a sectional view on the line 22 of Fig. 1; Fig. 3 is a partial vertical sectional view showing the relation of the parts with the reciprocating stone holder removed; Fig. 4 is a horizontal sectional view showing the inoperative position of the elements used for retaining the movable stone and the carriage therefor in elevated position; Fig. 5 is a similar view showing these elements in operative position.

The machine comprises a table of any desired size or material consisting preferably of a flat top 1 and suitable supports 2, the opposite ends of the table being provided with fixed uprights 3 which are of channel formation, one side 4 of each of the uprights being extended and being provided with a series of oppositely positioned notches 5, which notches are adapted for cooperation with a movable member on the carriage (to be later described) whereby the movable Specification of Letters Patent.

stone may be supported remote from the paper.

The table is preferably provided with suit able bearings 6 adapted to support a roll of paper 7, the paper extending over the top 1, and being thereby positioned for polishing by a suitable stone in a manner well known in the art. The top 1 of the table is provided with a fixed board 8 secured in position in any desirable manner but preferably between fixed guides 9, the board being located between the uprights 3; the table may be also provided, if so desired, with a suitable winding device for taking up the paper already treated or the paper may be wound on any other suitable ma chine or taken care of in different ways.

Positioned in the uprights 3 are the standards 10 connected at their top portions by the bar 11 and further provided with another transversely extending bar 12, one side of each of the standards being serrated. or notched, as at 13, in order to form a rack; rotatably mounted in any suitable manner on the table and preferably beneath the top 1 is a shaft 14 having a cog wheel 15 adjacent each end, the cog wheels being in en gagement with the racks 18, the outer end of the shaft being provided with a hand wheel 16 so that turning of the hand wheel will raise or lower the standards 10, thereby lifting the transverse bars 11, 12, and the movable stone carried thereby.

Slidably mounted between the bars 11, 12, is the holder 17 having a fixed jaw 18 and a movable jaw 19 carried thereby, the jaws being adapted to hold a stone 20 in position for engagement with the top of the paper 7, the opposite side of the paper being in em gagement with the before-mentioned fixed board 8. In order to removably hold the stone in position any suitable means may be provided for moving one jaw relatively to the other, in this case, the said means comprising an adjustable bolt 21. The holder 17 reciprocates back and forth between the bars 11 and 12 and, in order to impart a reciprocating motion thereto any suitable and desirable means may be employed, the preferred form, however, embodying a pitman 21 actuated by a suitable crank or pulley.

From what has been said it will be apparent that the stone 20 may be brought into inoperative or elevated position by turning the hand Wheel 16 whereby the standards 10 are elevated; in order to hold the standards and the transverse bars with the stone car ried thereby in such elevated position I make use of suitable means, preferably the following construction. A third bar 22 which I term a carriage is provided at its opposite ends with openings 23 through which the sides 4 of the uprights 3 are adapted to pass. This carriage 22 is provided with a locking plate 23 movable lon gitudinally thereon, the locking plate being provided adjacent each end with a longitudinally extending slot 24 communicating with an end recess 25 and an intermediate recess 26. The end recess 25 is of such dimensions that the side 4 of the uprights 3 may easily pass therethrough while the intermediate recess 26 is of such dimensions to receive a portion of the side 4 included between opposite notches 5 whereby, when the parts are elevated, they may be retained in such elevated position by movement of the locking plate 23 from the position shown particularly in Fig. 4 to that shown in Fig. 5; the method of connection between the locking plate and the third bar may be any thing suitable but preferably comprises a pin 27 extending upwardly from the bar and the cooperating slot 28 in the locking plate.

The connection between the carriage or third bar 22 and the transversely extending bar 11 and the standards 10 may be rigid or may be flexible, the preferred form being flexible or adjustable and involving the provision of screws 29 provided at their upper ends with hand wheels 30, the lower ends of the screws being rotatably secured to the transverse bar 11 by means of suitable fixed plates 31. Each of the before-mentioned longitudinally extending slots 24 in the slidable locking plate 23 permits the screws 29 to. be operated independently of the locking plate, the length of the slots 21 being such that the locking plate may move relatively to the third bar 22 without interferring with these screws.

With the machine in the posit-ion shown in Fig. 1 the movable stone 20 may be brought adjacent the paper 7 by moving the locking plate 23 toward the left, thereby bringing the intermediate recesses 26 out of engagement with the opposite notches 5 in the sides 4, the stone and the parts carrying it then falling into a lower position with the third bar 22 adjacent the tops of the end members of the fixed uprights 3; with the parts in this position the locking plate is then moved to the right in order to secure the parts and the position of the stone with respect to the surface of the paper 7 may be varied or properly adjusted by means of the screws 29,

movement of the screws not affecting the thlrd bar 22 inasmuch as its position is fixed by reason of theengagement of the locking plate with the notches 5. When it is desired to raise the stone entirely from the paper and through a suitable distance in orderto enable the paper to be changed or removed or the parts 'to be overhauled the locking plate is moved to inoperative position, the hand wheel 16 on the table is used to lift the standards 10 along with the transversely extending bars and the stone holder, the removed position being maintained by engagement of the locking plate in suitable notches. The construction and operation of the parts is such that these changes may be made, if necessary, with the movable stone reciprocating between the bars 11, 12. It will be noted that the stone 20 having been once adjusted with respect to the fixed board 8, this movable stone and the parts in operative relation thereto may be moved from the fixed stone without destroying or affecting the said adjustment.

The size of the machine and the different parts thereof will depend primarily upon the size of the material with which it is to housed; the particular form of pitman 21, it

together with the particular means for moving the pitman is not essential; the carriage 17 that supports the movable stone 20 may be reciprocated in many different ways, such means not being included within my invention, the scope of which is set forth in the appended claims.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent 1.
